Abstract: An apparatus and process for coating a plurality of articles in batches, in particular for applying a biocompatible layer on articles adapted to come into contact with blood or body tissue, e.g. a coagulation-preventing substance so as to render the articles non-thrombogenic. A plurality of article-carrying plates (14) are stacked upon one another and have a plurality of communicating wells (18) for receiving therein a respective article to be coated. A base plate (12) defines with a bottom side of a lowermost of said article-carrying plates a distribution chamber (34) for receiving and evenly distributing a solution containing a substance to be applied to said articles. The solution is fed through the wells of the stacked plates (14) in parallel vertical flows.
